MusicNet is a new publicly available dataset from UW CSE and UW Statistics researchers that “labels” each note of a classical composition in ways that can teach machine learning algorithms about the basic structure of music. It draws from 330 freely licensed classical recordings and uses dynamic time warping to precisely mark the start and stop times and the instrument that plays each individual note.
